Survey Work, Bug Fixes, and Changes for Consistency

modules/survey.py
       - consistency fixes
       - make addQuestion function more "general"
       - improve the "default case" if a user doesn't enter a priority question code in creating a template. Avoids a cryptic map error and instead provides a default numeric priority question - sort of like the Assess module.
